Astaxanthin – The Natural Red Pigment
Imagine eating a red pepper or seeing a pink flamingo. Both have something in common: a special red pigment. It’s called astaxanthin, and it’s found in many things around us. What exactly is it? Come, let’s take a look!
1. What Is It, Exactly?
Astaxanthin is a natural substance that you can think of as a tiny red protective shield. It belongs to the group of compounds known as carotenoids—pigments that give plants and animals their vibrant colours. You may be familiar with carrots, which are orange due to a carotenoid. However, astaxanthin is even more potent than many others and, for example, gives salmon their pink hue. It is also produced in your body, but only in very small amounts. Researchers suggest that astaxanthin is particularly effective at shielding other substances from damage—like a parasol protecting you from too much sun. However, exactly how this works is still under investigation.
2. Where Does It Come From?
Astaxanthin is primarily found in nature: in algae that grow in water, in salmon that feed on these algae, or in krill—small crustaceans in the sea. Flamingos also turn pink because they eat krill and algae containing astaxanthin. Sometimes, astaxanthin is extracted from algae to be used in powders or capsules. But don’t worry: it’s not some magical substance, just a natural component that animals and plants have been utilising for a long time.
3. What Are Researchers Investigating?
Researchers have conducted over 1,000 experiments with astaxanthin, but only a small fraction of these involved human subjects. They are exploring questions such as: Does it help protect skin exposed to excessive sunlight? Can it safeguard cells in your body? Or might it reduce inflammation? Some findings are promising, but not all questions have been answered yet. Researchers say there is still much to discover! Perhaps you’ll make a breakthrough yourself one day.
4. A Thought Experiment
Take a look at a salmon—it’s pink on the inside, isn’t it? Imagine if you could ask it: Why are you pink? It might reply: Because I eat tiny crustaceans and algae that contain astaxanthin! Try this: if you eat a carrot, does your skin turn orange? No, right? But why does the salmon turn pink? That’s the magic of nature—and precisely what fascinates researchers!

Frequently Asked Questions
Can I eat astaxanthin?
Yes, but only in small amounts. It’s found, for example, in salmon or trout. Your body doesn’t need it specifically, but it’s part of a healthy diet—just like vitamins. Simply eat a varied diet, and you’ll get everything you need.
Why do flamingos turn pink?
Flamingos eat small crustaceans and algae that contain astaxanthin. This gets deposited in their feathers and makes them pink. Without this food, they would be white or grey. Nature has some cool tricks, doesn’t it?
Can astaxanthin make me stronger?
No, it can’t. It’s not a magic potion that will suddenly make you super strong. Researchers are looking into whether it might help in other ways—for example, by protecting cells. But this isn’t certain yet.
